This 3Racing option part replaces the standard suspension mount on the TAMIYA TRF 415 chassis with a machined aluminium alternative designated 1D Ver. 2. It is an RC-scale accessory designed to offer a firmer mounting point for the TRF 415 suspension system while keeping chassis compatibility explicit to that model.
Installation is straightforward for experienced hobbyists: remove the stock mount and fit the aluminium piece to the same suspension attachment points. Use the original fasteners and confirm alignment before final torque to avoid binding in the suspension travel. No additional tools or hardware are included unless specified by the seller.
In setup and tuning, a metal mount provides a different stiffness characteristic compared with plastic parts, which can affect suspension geometry feedback during testing. Use it when you want a consistent mounting reference for adjusting shock positions, camber links, or roll center changes on the TRF 415 chassis.
Care and maintenance are simple: inspect the mounting faces for burrs after installation, keep fasteners secure, and check anodized surfaces for wear if the part is used in frequent track testing. This item is intended solely for RC model use on the TRF 415 chassis.
